adcs-attacks

Active Directory Certificate Services (AD CS) escalation techniques ESC1 through ESC17, driven by hand with Certipy (ly4k). Use when the target runs a Certificate Authority and you want to find vulnerable certificate templates or CA misconfigurations, request a certificate that impersonates a privileged user, and know the exact certipy command, what each ESC actually checks, the Windows Event IDs that fire, and the remediation. ESC1 and ESC8 are the two you hit most in the field.

# AD CS Attacks (ESC1–ESC17)

AD CS is the single richest privilege-escalation surface in modern AD. A misconfigured template or CA lets a low-privileged user obtain a certificate that authenticates as a Domain Admin. This skill uses **Certipy** (the `ly4k` project) throughout. You drive it by hand.

The whole thing starts with one enumeration pass. Run it first, read the output, then pick the ESC that applies.

```
certipy find -u user@corp.local -p 'Password123' -dc-ip 10.0.0.10 -vulnerable -stdout
```

Certipy names each finding by its ESC number, so the tool's output tells you which of the below applies. Save the full JSON/BloodHound output for the report:
```
certipy find -u user@corp.local -p 'Password123' -dc-ip 10.0.0.10 -vulnerable -old-bloodhound
```
